Why can lift blocks be used at the front axle?
Using lift blocks on the front is never a good idea because: • When used on the front axle, blocks are subjected to increased side loads when cornering, which can cause them to fail by “rolling out” from under the springs. This, in turn, will cause loss of vehicle control. • Most blocks are tapered. If the tall end is installed facing towards front-of- vehicle, it worsens caster angle; if the tall end faces rear it worsens driveshaft angle. • Most factory front springs are fairly weak. Blocks increase the leverage load on these already weak springs which really compounds spring / axle wrap-up.
